In this Tuesday, February 11, 2014, photo, a trained monkey, that makes a living for her Pakistani owner by performing to a crowd in public and private places, sits held by a leash, in Rawalpindi, Pakistan. For Pakistanis who raise and train the monkeys they are an important source of income in an impoverished country, and they form a strong bond with the animals. The monkeys are usually captured in the wild when they are babies and then trained. A trained monkey can fetch 20,000 to 30,000 rupees ($190 to $285). (Photo by Muhammed Muheisen/Associated Press)

Rush-hour in Russia means one thing for this daredevil: train surfing! The 19-year-old daredevil who goes by the name Kobzarro started train surfing aged 15 as a way of escaping an oppressive family life. Here Kobzarro can be seen balanced on top of a train as it speeds through the wintery Russian environment. Kobzarro is so dedicated to train surfing that she rarely gets inside a train. Even in winter she prefers to travel in this less conventional way. It has resulted in a few run ins with the law, but Kobzarro says it has never resulted in anything more serious than a fine, with many police officers even being interested in the train surfing community.
